This stuff http://www.screwfix.com/p/cementone...kg/5604h#product_additional_details_container Need to put a bit down to finish off a freshly concreted screed over an old hearth. I've read somewhere that it requires the surface to be primed but no mention of what to use? Anyone advise please? Ta.
Hi Fred Not actually used it myself (yet) but looking to level my garage floor so done a little research Wickes sell 'Setcrete Floor Leveling Primer' , which seal porous, dusty surfaces prior to pouring the levelling compound Around £12 I remember but will probably be way too much quantity for your small area but ........ Don't ever be tempted to use PVA ...... may well end in tears mate
And a linky: http://www.wickes.co.uk/Setcrete-High-Performance-Floor-Levelling-Primer-2-5L/p/154148 Good advice pva & levelling compound will end in a disaster.
Spotted this while following your link. http://www.wickes.co.uk/KA-SBR-Bond-1L/p/139061 Bit cheaper and only need a small quantity. Looks like it will do the job. Says it can be added to screeds or applied as a bonding agent. Am I missing something daft?
Perfect, dilute at 3 to 1 or 4 to 1, I didn't recommend SBR, as usually it's on comes in 5ltr can, & couldn't find in a smaller amount, good to see Wickes doing a 1ltr can. The great thing with using SBR is it doesn't re-emulsify like PVA wet you wet it.
Thanks for the advice KIAB. I can't see any instructions, do you just know about the dilution from previous use of something similar?
Use it for years,leveling compound at previous place was down for years,& still is, & never lifted, here it's be down seven years. Depending on the suction of the surface you can vary the dilution rate up to 8 to 1 if it's a porous surface, usually one coat is enough, but you can let it dry & apply a second if need be. Regardless of brand of SBR, I dilute I as see fit for the job. Found a linky. http://www.chilternslurry.com/wp-content/uploads/2015/12/Technical-Data-SBR1.pdf
Normally I'd just use a standard acrylic primer but SBR will definitely do the trick; just get your levelling compound down whilst the SBR is still tacky to the touch
Difficult finding acrylic primer in 1ltr can,only know of Topps Tiles selling it, but Wickes 1ltr SBR is half the price.
True, I didnt think of that. I usually just get 5ltr tubs as they'll get used up on other jobs eventually.
Same here. Trouble is a lot of additives are 5ltrs & geared up for trade use, I think firms like Everbuild are missing a niche in the market not doing say 2.5ltr, even 1 ltr can of products like 204 Evermix 3 in 1 or 406 Stabilishing Solution for diyer's.
Evening all. First-time poster Can I double-check I'm getting this right? I have a VERY dusty workshop floor that I want to seal and level. If I'm understanding the post correctly, I use this stuff first http://www.wickes.co.uk/Setcrete-Hi...ling-Primer-2-5L/p/154148#tab-reviews_content and then put this stuff on top, ideally while the primer is still wet http://www.wickes.co.uk/Setcrete-Deep-Base-Floor-Levelling-Compound-20kg/p/133780. It's proving impossible to clean the surface prior to priming as any sweeping just lifts more cement dust - will that be a problem? Any tips for getting round this? I'm not going to be adding any vinyl or carpet, so I'm just hoping that this stuff will work ok as a wearing layer. Thanks matt
If the floor is really bad I would look to use something like Everbuild's "Concrete Hardener and Dust-proofer", the down-side being that you need to wait another 28 days before primering and screeding.
The majority of levelling compounds are for simply er, well, um, levelling and are not recommended to be used as the finished layer Strongly advise that you check all product details regarding this point to check suitability Could always go over compound with T&G chip flooring or OSB 3, then a couple coats of floor paint if you want. Any suspicion of damp from floor then add a poly membrane
If you want a levelling compound as a wearing surface, then a industrial floor screed which needs to be polymer resin based, not latex based. A polymer resin screed will give you a very hard surface and can be applied to only 3mm thick if required.
How large is the area. Regardless of levelling compound, most surfaces need to be dust free before it's layed.
I've used this stuff before for garages - gives a decent wearing surface too, as opposed to standard floor screed http://www.larsenbuildingproducts.com/products/range/3/category/47/-/0/product/245/
Now thank is a useful linky, thanks. Nice, it's a one part product, some of the industrial compounds are two or three parts. Still need to use a acrylic primer before laying it.
That looks like just the job - thanks very much KIAB. So... Current thoughts are to use Everbuild's "Concrete Hardener and Dust-proofer" first to contain the dust, as suggested by Rob_bv. Leave for 4 weeks. Then some acrylic primer, then the SLC2000 same day. The area is 18m sq. Thanks folks. Really useful info
